ATTACHMENT FOR AUTOMOBILE RADIATOESJ Application filed August 11, 1920. Serial NO.. 402,887.

To all whom it may concern:

Be it known that I, HORACE A. DILLARD, a citizen of the United States, residing at Burns, in the county of Harney and State of Oregon, have invented certain new and useful Improvements in Attachments for Automobile Radiators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enableothers-skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in attachments for motor vehicle radiators and has for its primary-object the provision of means adapted to utilize the, escaping steam from a frozen radiator for the purpose of thawing the same and prevent further freezing thereof during the will become more apparent as running of the engine. a I

Another object of this invention is the provision of a pipe equipped at one end with means for detachably securing it to the end of the overflow pipe of the radiator, and has its other end disposed in close proximity to the discharge pipe and the lower portion of the radiator, so that the steam from the radiator may be directedon the portion of the radiator in which the water becomes frozen'for the purpose of bringing about free circulation of the water to the engine.

A- further object of this invention is the provision of an attachment for a motor vehicle radiator of the above stated character, which shall be simple, durable and eflicient, and which may be manufactured and sold at a comparatively low cost.

With these and other objects in view as the description proceeds, the invention consists in certain novel features of construction, combination, and arrangement of parts as wil hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure l'i's a an attachment or motor vehicle radiators constructed in accordance with my invention, I

' Figure 2 is a rear elevation of a radiator illustrating my invention applied thereto.

' Figure 3 is a detail sectional view illustrating the means of securing the pipe to the lower end of the overflow pipe of the radiator.

erspective view, illustrating Referring in detail to the drawing, the numeral 1 indicates a'radiator for use in con Junction with the engine of a motor vehicle for the purpose of cooling said engine and has the usual discharge pipe 2 adapted to be connected-with the Water jacket of the engine (not shown) and the return pipe 3. The radiator is also provided with the usual overflow pipe 4: that extends from the upper portion of the radiator to a point adjacent the lower end of the-radiator for the purpose of permitting excesswater to escape from the radiator and also steam. It is well known that the first place in which the water of the radiator becomes frozen is in the discharge pipe 2 and the lower portion of the radiator and when the water becomes frozen, the circulation through the water jacket of the engine (not shown).is"stopped and what water there may be in the'water jacket becomes highly heated during the running of the engine, causing a generation of steam, which escapes into the upper end of the radiator by the return pipe 3 and thus escapes from the radiator by way of the overflow ipe 4.

To utilize the escaping steam for the purpose of thawing the radiator during the running of the engine, I have provided a pipe 5 which has one end curved as illustrated at 6 and'secured to a split sleeve 7. The split sleeve 7 is positioned on the lower end of the overflow pipe 4 and is provided with a fastening element 8 which passes through a pair of apertured ears formed integrally with the split sleeve for the purpose of tightly securing the sleeve 7 above the end of an overflow pipe 4. The other end of the pipe 5 is disposed in close proximity to the discharge pipe 2 of the radiator and also the lower portion of the radiator and is supported in such a position by means of a bracket 9 which is soldered or otherwise socured to the radiator. The bracket 9 is provided with an opening which the pipe 5 extends through and on being secured to-the radiator prevents the free end of the pipe 5 from becoming disarranged or moved away of the radiator and from by way of the overflow pipe 4 and through the pipe on to the discharge pipe 2 and against the lower portion of the radiator, thus thawing the radiator permitting the reestablishment of the circulation of the water through the jacket of the engine and the radiator. This device will immediately bring about the thawing of the radiator at any time whenthe water of the radiator becomes frozen and the water in the jacket of the engine becomes heated to such a degree that steam will be generated.

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction combination, and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus describe'dmy invention what I claim is 1. An attachment for automobile radiators including an overflow pipe, a curved pipe, a-bracket secured to the curved pipe and to the radiator for supporting one end thereof in close proximity to the lower portion of the radiator and its dischargepipe, a split sleeve secured to the other end of the curved pipe and receiving the lower end of the overflow pipe,;and a iastening means s'ecuring the sleeve to the overflow pipe.

2. An attachment for automobile radiators comprising a pipe, a bracket attaching the pipe to the lower portion of a radiator and supporting one end thereof in closeby the other end of the pipe and receivingthe lower end of the overflow pipe of the radiator.
